Gradle，“sourceCompatibility” vs“targetCompatibility”？ [英] Gradle, "sourceCompatibility" vs "targetCompatibility"?

问题描述

sourceCompatibility 和 targetCompatibility 之间的关系/区别是什么？当它们设置为不同的值时会发生什么？

根据 Gradle文档：
$ b sourceCompatibility 在编译Java源代码时使用。
targetCompatibility 是用于生成类的Java版本。

我的理解是 targetCompatibility 将生成与特定版本的Java兼容的Java字节码，这是 sourceCompatibility 的功能的子集吗？

解决方案

这通过映射到javac - 参见交叉编译部分 - 源代码基本上是源语言级别，目标是生成的字节代码级别。

What is the relationship/difference between sourceCompatibility and targetCompatibility? What happens when they are set to different values?

According to Gradle documentation:

sourceCompatibility is "Java version compatibility to use when compiling Java source." targetCompatibility is "Java version to generate classes for."

My understanding is that targetCompatibility will generate java bytecode that is compatible with a specific version of Java, is this a subset of the functionality of sourceCompatibility?

解决方案

this maps through to javac - see the cross compilation section - source is basically the source language level and target is the level of the bytecode that is generated.
